A universal do-not-track tool, endorsed by the FTC in a report focused on online privacy released Wednesday, could make online targeted advertising less effective and could slow the growth of e-commerce, one of the few bright spots in an otherwise stagnant U.S. economy, said Representative Ed Whitfield, a Kentucky Republican, during a hearing of the Consumer Protection Subcommittee of the U.S. House of Representatives Energy and Commerce Committee.

Consumers would likely rather get relevant ads than irrelevant ones, he said. "The question is, is the government really the entity to make that decision?" Whitfield added. "Would an [online] advertising model be sustainable in the absence of marketers' ability to track?"

Web users with a do-not-track tool enabled may see a significantly different Internet than ones that accept tracking, added Joseph Pasqua, vice president of research at security software vendor Symantec. "A user with the no-track option enabled may be fed websites with limited content, while other users without the option set would see a richer Web page and have a more robust browsing experience," he said in his subcommittee testimony.

Personally, I don't like myself being tracked. Good read.
